I also choose photos.
Cos the photos are going to stay with us for long. And we can always take it out and recall it together...
While the rest are only a one day memory while few years down the road, people or even ourselves might even forgot part of it...

I think there are 2 things that I will look into. One if photo, which is for my memory and keepsake, the other is the wedding venue; especially the ballroom. I've encounter various weddings whereby there are pillars blocking the view etc, and I often heard complains about it. So for my venue, I will want it to be un-blocked as much as possible. It's for the guests, cos I want them to enjoy the day as much as I do, and not complaining about this and that. Though it;s hard to avoid those kinda comments, just minimize it as much as possible!
